In the last years, issues concerning water saving in water distribution systems have paid interest through an integrated policy aiming at reducing leakage by means of pressure control. Hence, in water distribution systems Pressure Reducing Valves (PRVs) are often used to prevent the downstream hydraulic grade from exceeding a set value. Nevertheless, PRVs must be strategically placed to maximize their effectiveness. In recent years the application of turbines or pumps operating as turbines (PATs) appeared as an alternative and sustainable solution to either control network pressure as well to produce energy. In the present paper PRVs and PATs were used to control pressure within a district of Naples water distribution network, showing large potential revenues of PATs and an attractive capital payback period.
